Finite element analysis of photonic crystal fibers

Abstract

Photonic crystal fibers present a new way to guide light The air holes in the fiber work as a cladding, but provide much more flexibility in the design. In this work, the finite element method (FEM) is used to analyze photonic crystal fibers, providing the basic tools for calculating parameters such as mode effective index, mode effective area and dispersion. The results of a design sample are presented in this article, showing the potential of using FEM to analyze this new class of fiber.
